Yes, indeed, Arne. Our local manufacturer, Altex, makes polyurethane paints that can be mixed to any colour. You need to go to a trade shop to get this done because we are talking of commercial products here. We have a great place in Whangarei, who also gives you a 'trade' account, ie 15% off, if you go there often enough. My friendly, neighbourhood chandler used to work for paint manufacturers and he, too, will mix to any colour. Being commercial products, they don't have the 'brushability' of something such as International Perfection, but with perseverance one can achieve at least acceptable results.
